Stainless Steel for Alloy Brushes

Precautions and Safety Instructions


Steel bristles produce sparks which will ignite volatile solvents or vapours.

You are advised to wear eye protection when using the brush as fine particles or solvent droplets can be propelled from the work area at high speed.

Do not use near live electrical cables or terminals.

Do not use near hot engine or machinery parts.

For use by hand only, not to be mounted in power tools.

Usage Directions - SS for Alloy Brushes

The area to be worked on must be free of oil, grease and grime - the smallest amount can be spread a long way. Wash well with detergents or degreaser. The nylon bristle brushes are ideal for this purpose

Practice the refinishing technique first on an old alloy casting or an inconspicuous part of your motor

The brushes are used dry

The brush should be held like a pen almost perpendicular to the alloy surface and whilst pressing down firmly move in all directions with very short strokes

The fine bristle tips penetrate the tiny pits and depressions. Vary the angle of the brush to allow the bristle tips to contact all of the surface

Work the brush evenly in all directions. Aim to cover a small area about the size of your thumbnail thoroughly and then work outwards from there

You will note the bite of the brush varies when moved in different directions. This is due to the crimp or bends in the bristles and can be used to great advantage at times

Try to avoid bending bristles back when inserting into thin grooves or crevices, and do not push the brush forwards at a shallow angle

After brushing an auto wax applied with a clean cotton cloth helps maintain the lustre

Refinishing the Flat Surfaces of the Fins

These notoriously difficult areas can be refinished by brushing but the shallow angle of approach means that only some of the bristle ends can brought into contact with the alloy and you will need to be very patient

The thinnest brush, size A, is best for this as it can be angled a little between the fins

The bristle ends can be bent to one side which allows more bristles to touch the flat surface at once. The most practical way is to use a green 3M ScotchBrite pad with a household abrasive first then use the brush on any areas which require further attention

Cleaning Brushes

If brush gets clogged with grease or grime drag the bristles backwards on rough concrete or old carpet. Rotate the brush as it is dragged backwards and most of the debris will be gone

Brushes may be washed in suitable solvents ( compatable with epoxy resin ) or hot water and detergents. They may be placed in boiling water or autoclaved, but do not use until cool

Shake out any liquid from handle. Store dry

Reshaping the Bristle Tips

Even the most carefully used SS for Alloy brush will end up looking like an old mop sooner or later

To reshape tips find a right angle join such as where a brick wall meets a concrete floor, or put a piece of hardwood on the floor and drag the bristles backwards along in the join, pressing hard and rotating as you go

Rejuvenating your Brush

The bristles are extremely durable, but eventually will wear down or fatigue. They are secured at the base of the handle and a new working set of bristles can be revealed by removing a section from the work end of the handle. Each brush can be renewed several times

Use sharp tinsnips or scissor-type cutters to trim off the old tips - give them a short haircut so the handle section can be removed easily

Make a groove around the handle about 12 mm. from the working end with a triangular file or tube cutter. Complete the circular groove down to the bristles, break off and discard the brass section

Cut newly exposed bristles with sharp tinsnips or cutters to suitable length. Do not exert any pull on the bristles whilst making the cut

As a guide the free bristle lengths for new brushes are -
Size A - 6mm, size B - 7 mm, size C - 8 mm and size D - 9mm
Try to keep close to these lengths as shorter bristles have more bite than required and longer are too soft to be effective

The newly cut bristle ends will have very sharp edges and must be worked in by rubbing on concrete or brick in all directions before use on soft metals. Your brush is now ready to perform as new.


The brushes are hardy and quite happy in the toolbox or on a shelf but beware of finger injuries from the fine bristles when fishing around. Shown below is the brushmaker's set of 8 which fit nicely inside a piece of 1 inch mailing tube
